I can't read that language but I'll guess it says write a second degree equation then solve for n when d=10.



Answer: n² - 3n - 20 = 0
That doesn't factor so there is no integer n solution.
That means there are no polygons with 10 diagonals.

Answer:
150 by 100
Step-by-step explanation:
Answer:
Point Form:
(0,4)
Equation Form:
x=0,y=4
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
If she took $20 out of her savings account, given the information, she could easily have no money remaining now. Given this, we'll assume the current value of her account is the minimum it can be. Now you just need to find how many times her withdrawal can factor into the original amount, $250. Therefore, t=250/20= 12.5. Since it's asking for a number of weeks, the answer can't be a decimal, so your final answer is 12 weeks.
Answer:
4.11 (rounded to the hundredth place, the actual answer is 4.1(with the one repeating))
Step-by-step explanation:
To solve 37 divided by 9 you have to do long division or you can use a handheld calculator.
To solve it through long division,
9 can go into 3 zero times
9 can go into 37 four times though
9*4 is 36
So subtract 36 from 37, leaving 1.
9 can go into 1 zero times.
Add a zero behind the one and 9 can go into 10 once.
The pattern continues forever, making the answer 4.1(with the one repeating)
or 4.11 (rounded to the hundredth place)
If you need anymore clarification I can certaintly help.
